Pipeline double-row deformation detection mechanism

Abstract

The invention relates to a pipeline double-row deformation detection mechanism. A front leather cup and a rear leather cup are connected to the front and rear ends of a cylinder through a front bracket and a rear bracket respectively. Two rows of sensing arms, with one row behind the other, are arranged outside the cylinder. Each row of sensing arms is composed of multiple independent sensing arms circumferentially distributed at equal intervals. The two rows of sensing arms are alternately distributed back and forth. Each sensing arm is hinged to a pin shaft through a support connected to the cylinder. The outer end of each sensing arm is equipped with a sensing body. The supports and the sensing arms are connected by torsion springs and form sensing arm expansion fit. An angular displacement sensor and a sensing block are arranged at the joint of each sensing arm and the corresponding support. A speedometer is arranged on the cylinder or on the brackets. A sealed cabin is arranged inside the cylinder. The mechanism has the characteristics of high detection resolution, compact structure, high reliability, fast response of the sensing bodies, high detection accuracy, strong ability of obstacle crossing inside a pipeline, convenient maintenance, and the like.

AI Technical Summary

Benefits of technology

This technology helps prevent damage or malfunctions caused by pipelines that may have changed over time due to factors like temperature changes (thermal expansion) or pressure differences between different parts of the pipe system. By monitoring these issues with multiple sensors placed at specific locations around the circumference of each part of the structure being monitored, this innovation allows for more efficient use of resources while maintaining safety standards.

Problems solved by technology

This patented technical problem addressed during developing an effective method for detecting flaws (such as cracks) along a pipeline' s inner surface is finding any signs of damage caused due to environmental conditions like temperature variations overshootings, pressure differences between different parts of the system, etc., which could lead to leaks when they occur. Current methods require manual inspections with tools called guided missile guns equipped with sensors, but these are often limited because they only work at specific points within the pipeline.
